17.4.1 Cleaning Or Replacing The 4R+ PID

1. Gently lift out the PID module with your fingers.
2. If the module requires replacement (because the lamp does not illuminate, or the module has been
used past its expiration date), place a new module into the slot, being careful to match the
indexing keys. The sensor can only go into its slot one way. Refer to step 11 for alignment
information.
3. If you want to open the sensor module to inspect and clean the lamp and sensor electrode panel,
you must use the special tool (P/N: G02-0306-003). The special tool's "C"-shaped end has small
"teeth" inside. Slide the tool so that the teeth slip into the notch between the module's cap and
body:
4. Gently pry up the cap using a rocking motion:
5. Once the cap is removed, set it aside.
